Thanks lear, I appreciate you taking the time to reply. I love this bike its at 10 and 1/2 to one compression but was thinking i might be able to get 5 hp more. Hey we cant win em all, but thanks again for your reply.
Hello all, I recently built my 2003 650l. Big bore kit,pipe, cam, flat slide carb,porting and polishing,cutting airbox and one tooth smaller on countershaft. I had it dyno tuned and it is putting out 46 hp and 38 pounds of torque. Is there a way to increase horsepower from here. This seems like a never ending battle but thought someone might have a suggestion?
